Grammatotria lemairii is a species of cichlid endemic to Lake Tanganyika in East Africa where it prefers areas with sandy substrates. This species can reach a length of 26cm (10inches) TL. It is currently the only known member of its genus. The species is occasionally kept as an aquarium fish.[1] The specific name honours Lieutenant Charles Lemaire (1863-1925) who was the leader of the Congo Free State Expedition, which collected specimens of fishes at Lake Tanganyika, including the type of G. lemairii.[2]
